DETAILED DESCRIPTION OF THE INVENTION

The present invention contemplates a floral cover which is manufactured from a flat sheet of material by folding and securing portions of the sheet of material in a particular sequence into the shape of a tubular sleeve which is then formed into an opened container to contain a pot, floral grouping, botanical item or growing material. It will be appreciated that the examples of the invention provided herein are not intended to limit the scope and extent of the claimed invention but are only intended to exemplify various of the embodiments of the invention contemplated herein.

Referring now to the drawings, FIGS. 1-9 show a process of folding a sheet of material 10 into a decorative cover 108 (FIGS. 8-11) which can be used to contain a potted plant, floral grouping or botanical item.

The sheet of material 10 (also referred to herein as sheet 10) shown in FIG. 1 and in FIGS. 2-9 in various stages of folding, has a first apex 12, a second apex 14, a third apex 16, a fourth apex 18, a first edge 20, a second edge 22, a third edge 24, and a fourth edge 26. The sheet 10 has a first fold line 28 (which may or may not constitute an actual crease or scored line) which extends between third apex 16 and fourth apex 18. The first fold line 28 effectively separates the sheet 10 into a first triangular portion 30 which comprises the portion of sheet 10 between the first fold line 28 and the first apex 12, and a second triangular portion 36 which comprises the portion of the sheet 10 between the first fold line 28 and the second apex 14. The first triangular portion 30 has an inner surface 32 and an outer surface 34 (e.g., FIG. 2). The second triangular portion 36 has an inner surface 38 and an outer surface 40 (e.g., FIG. 3). A first connecting bonding material 42 such as an adhesive is disposed upon a portion of the inner surface 38 of the second triangular portion 36, preferably near the fourth apex 18 for bondingly connecting the first triangular portion 30 to the second triangular portion 36. Alternatively, the first connecting bonding material 42 could be disposed upon a portion of the inner surface 32 of the first triangular portion 30 for bonding the first triangular portion 30 to the second triangular portion 36. Alternately, when the first connecting bonding material 42 is a cohesive material, it may be disposed on portions of both the first triangular portion 30 and second triangular portion 36.

In a first folding step, the first triangular portion 30 is folded upon the second triangular portion 36 in a direction 44 resulting in the sheet 10 being folded into two triangular halves: a first folded portion 48 and the second triangular portion 36, as shown in FIGS. 2 and 3. The first folded portion 48 is the first triangular portion 30. The sheet 10, now folded, has a first corner 50, generally in the same location as the third apex 16 and, a second corner 52, generally in the same location as the fourth apex 18. The connecting bonding material 42 connects the first folded portion 48 to the second triangular portion 36. The first edge 20 is adjacent and parallel to the third edge 24, and the second edge 22 is adjacent and parallel to the fourth edge 26. The first apex 12 is adjacent the second apex 14. A bottom edge 54 of the sheet 10 extends between first corner 50 and second corner 52.

A second fold line 56 (which may or may not constitute an actual crease or score line) extends between first edge 20 and second edge 22 in the first folded portion 48. The portion of the first folded portion 48 between first apex 12 and the second fold line 56 comprises an upper triangular portion 58. In a second folding step, the upper triangular portion 58 is folded in a second direction 60 to lie against a portion of the outer surface 34 of the first folded portion 48 to form a second folded portion 62 (FIGS. 4 and 5). The second folded portion 62 (also referred to herein as the “apical portion”) has a left edge 64, a right edge 66, an upper edge 68, a first corner 70 and a second corner 72. When the second folded portion 62 in the first folded portion 48 is formed, a skirt portion 74 is formed in a portion of the first triangular portion 36 between the second apex 14 and the upper edge 68 of the second folded portion 62, the skirt portion 74 has an edge 76.

A third fold line 78 (which may or may not constitute an actual crease or score line) extends in the first folded portion 48 and the second triangular portion 36 between the second corner 72 of the second folded portion 62 and the bottom edge 54. The portions of the first folded portion 48 and the second triangular portion 36 which extend between first corner 50 and third fold line 78 comprise a left triangular portion 80. In a third folding step, the left triangular portion 80 is folded in direction 82 wherein first corner 50 is disposed generally adjacent the first corner 70 of the second folded portion 62 wherein the left triangular portion 80 forms a third folded portion 84 (FIGS. 6-7) and which is also referred to herein as the first corner portion, which entirely or substantially covers second folded portion 62 and a portion of the outer surface 34 of the first folded portion 48. The third folded portion 84 has a left edge 86, a right edge 88 which extends from first corner 70 of the second folded portion 62 to the bottom edge 54, and an upper edge 90 which is adjacent and generally parallel to the upper edge 68 of the second folded portion 62.

A fourth fold line 92 (which may or may not constitute an actual crease or score line) in the first folded portion 48 and the second triangular portion 36 extends between the first corner 70 of the second folded portion 62 and the bottom edge 54. The portions of the first folded portion 48 and the second triangular portion 36 which extend between the second corner 52 and the fourth fold line 92 comprise a right triangular portion 94.

Disposed upon a portion of the outer surface 34 of the right triangular portion 94 is a second connecting bonding material 96 preferably near second corner 52. The second connecting bonding material 96 is preferably disposed on the right triangular portion 94 but may alternatively be disposed upon an exposed surface portion of the third folded portion 84. The second connecting bonding material 96 may alternately be disposed upon portions of both the right triangular portion 94 and the third folded portion 84, for example when the second connecting bonding material 96 is a cohesive material. In a fourth folding step the right triangular portion 94 is folded in direction 98 wherein second corner 52 is disposed generally adjacent second corner 72 of the second folded portion 62 wherein the right triangular portion 94 forms a fourth folded portion 100 (FIGS. 8 and 9) and which is also referred to herein as the second corner portion, which covers a portion of the third folded portion 84 and a portion of the outer surface 34 of the first folded portion 48. The fourth folded portion 100 has a left edge 102 which extends from near the second corner 72 of second folded portion 62 to the bottom edge 54, a right edge 104, and an upper edge 106 which is adjacent and generally parallel to upper edge 90 of the third folded portion 84. The fourth folded portion 100 is connected to the third folded portion 84 via the second connecting bonding material 96. It will be understood by a person of ordinary skill in the art that the second connecting bonding material 96 may not be applied until just before the right triangular portion 94 is folded to form the fourth folded portion 100, or it may be applied to a portion of the sheet 10 well before the forming of the fourth folded portion 100, in a manner similar to the sheet 10 in the embodiment shown in FIGS. 1, 2 or 4.

The fourth folding step results in the sheet 10 having been formed into a decorative cover 108 (FIGS. 8-11) which comprises essentially two components, a base portion 110 constructed from the first, second, third and fourth folded

portions

48, 62, 84 and 100, respectively, and the skirt portion 74 which extends generally from the base portion 110, and beyond the upper edge 106 of the fourth folded portion 100. The base portion 110 preferably has a tapered, or frustoconical sidewall 112 when opened as shown in FIGS. 10 and 11. FIG. 10 shows a bottom view of the decorative cover 108 expanded from a flat condition to an opened condition.

The decorative cover 108 is opened manually or automatically and in a preferred embodiment is disposed over a pot-shaped mold or mandrel (not shown). Once disposed upon the mold or mandrel, the decorative cover 108 can be secured in an opened position by forming a first bottom fold 114 and a second bottom fold 116 in a lower end 117 of the decorative cover 108. The first bottom fold 114 and the second bottom fold 116 are secured by a bottom fold securing element 118 such as a tape, adhesive material, or heat seal thereby forming a substantially flat bottom 120 in the decorative cover 108. The decorative cover 108 is thereby formed into an opened position and has an upper opening 122 and an inner retaining space for containing a pot 126, which has an upper rim 128. A plurality of the decorative covers 108 thus formed can be stacked to form a nested set of decorative covers 108 for shipping.

As noted, the decorative cover 108 has an inner retaining space 124 (also referred to herein as an interior space) into which the pot 126 having a floral grouping 130 has been disposed. The skirt portion 74 extends a distance above an upper rim 128 of the pot 126 and the upper edge 106 is positioned, preferably, near a portion of the upper rim 128 of the pot 126.

FIGS. 1-9 show how the square sheet of material 10 is formed into the decorative cover 108 (also referred to herein simply as a “cover”) having the skirt portion 74, however, it will be apparent to a person of ordinary skill in the art that sheets of material having other shapes (non-square) could also be used to form decorative covers in accordance with the methods designed herein. Examples of such sheets of material and the decorative covers formed therefrom are shown in FIGS. 12-17.

Shown in FIG. 12 is a sheet of material 132 having a pentagonal shape (a truncated square) which when formed into a decorative cover 134 (FIG. 13) in the manner described herein lacks a skirt portion similar to the skirt portion 74 of decorative cover 108.

Shown in FIG. 14 is a sheet of material 136 which when formed into a decorative cover 142 in the manner described herein has a skirt portion 138 which has a non-linear or curved edge 140 (FIG. 15). Shown in FIG. 16 is a sheet of material 144 which when formed into a decorative cover 150 has a skirt portion 146 which has a non-linear or curved edge 148 (FIG. 17) which has a different configuration than curved edge 140.
